A technology company with on-premises AI-related operations, this organisation offers the opportunity to help shape the reliable, secure IT environment that enables its people and technical teams to do their best work. Its English-speaking technology team values practical problem-solving, hands-on ownership and close collaboration across functions. Engineers are encouraged to improve processes and systems directly, rather than relying solely on external providers.
Based in Tokyo, the organisation offers a flexible working schedule and remote working, with scope for more remote days depending on performance. The package includes annual leave, learning and development support, and family-related benefits. Team events and regular shared meals provide opportunities to build connections across the business.
Two Senior IT Engineers are sought to take hands-on responsibility for the day-to-day reliability, security and support of the corporate IT environment. The work is primarily office IT, with a smaller network engineering component, and covers endpoints, employee support, on-premises Linux servers, authentication systems and connected infrastructure. This is not a public-cloud infrastructure administration role; advanced DevSecOps platform work sits with a separate specialist.
You will manage devices throughout their lifecycle, support employee onboarding and access needs, maintain internal IT systems and records, and troubleshoot multi-site connectivity, WAN, VPN and network infrastructure. You will also implement security controls, support compliance and audit activities, automate routine tasks, and carry out first-line checks on containerised and Kubernetes-related workloads. Clear documentation, careful change management and effective communication will be important. One of the two hires will be appointed to a Manager role after joining, with selection details shared during the hiring process.
Demonstrable hands-on experience in corporate or internal IT, particularly endpoint and device management, employee support, access management and IT systems administration.
Practical experience troubleshooting and administering Linux environments and on-premises servers.
Sound enterprise networking knowledge, including L2/L3 switching and routing, TCP/IP, DNS, WAN, VPNs, firewalls and security gateways.
Ability to troubleshoot methodically, document procedures clearly and collaborate effectively with colleagues and external providers.
Business-fluent or fluent English for day-to-day work; Japanese is preferred.
Experience with configuration management or automation, ideally Ansible, and an interest in improving repeatable IT processes.
Familiarity with container and Kubernetes fundamentals, endpoint and network security, patching, vulnerability remediation or security monitoring.
Experience supporting multiple offices, complex WAN/VPN environments, on-premises AI infrastructure, or tools for containers, monitoring and logging would be an advantage.
For the management-track appointment, readiness to lead day-to-day work, coach colleagues, plan workloads and oversee escalations and compliance activities.
